The Trans Canada Highway (16th Avenue North) is a major east-west transportation route through Calgary connecting the provincial and national highway systems. Bowfort Road serves Canada Olympic Park to the south and residential/business districts to the north. The previous intersection was not capable of handling the traffic volumes generated by any large scale events or the 60,000 vehicles that pass through this area every day.

A major, two-year interchange upgrade was undertaken to widen the TCH and create a signal-free access to relieve one of the City’s most significant traffic headaches. AIL ‘s Precast Panel Walls became part of the solution.

From the outset, there were three main challenges to this project, but our Precast Panel Walls had all the angles covered:

Unique Panel Design
A truly unique aesthetic treatment was specified for this major project.

Limited Working Room
TCH traffic needed to remain flowing throughout construction, so the working area was limited.

Unique Panel Design
Our supplier, MSE Precast, did an unbelievable job executing the eye-catching beveled panel design that was specified. However, they had to make the pattern conform to hundreds of custom partial panels as well. Also, the uneven panels had to be stacked in an unconventional way before delivery. MSE Precast jumped through hoops to provide a quality product without issues.

Limited Working Room
By design, our MSE Retaining Walls can be assembled on narrow job sites with limited lay-down areas. We also worked with PCL to try and keep our Grid-Strip Soil Reinforcement lengths as short as possible.

Cold Weather Construction
We designed and used a special winter backfill material that is not susceptible to frost. This allowed PCL and Rino to work through the winter months to maintain the project schedule. Rino is a veteran contractor in MSE walls and their proficiency was a real plus on this challenging project.

AIL is proud to be partnering with Graham Infrastructure LP on Calgary’s $62 million Short-Term Improvements Project on the Crowchild Trail. Working very closely with the Graham team, we have been able to navigate a very complex three-tiered retaining wall design, an extremely tight site/schedule and winter conditions.

The AIL MSE Retaining Wall System is being used to build bridge abutments and retaining walls as part of an 18 km Highway 401 Expansion Project through the Peel and Halton Regions of the Greater Toronto Area (GTA). The widening project runs from the Credit River in Mississauga to Regional Road 25 in Milton, with widths growing to 10 and 12 lanes.

Atlantic Industries Limited (AIL) is proud to have been selected as a partner on a large design-build project for two interchanges in the City of Saskatoon. Our role was to design and supply MSE Precast Panel Wall bridge abutments. We also provided a temporary wire-faced shoring wall and precast concrete coping elements.

AIL's MSE Retaining Wall System and our in-house engineering team demonstrated their versatility in support of the new, 8 km LRT line that connects Calgary's downtown core with communities to the west.

When Calgary Transit’s Northwest C-Train line was extended past Crowfoot to a new station called Tuscany Station, our MSE Retaining Walls were brought in to support a Park-and-Ride, a pedestrian bridge and then some.

AIL received a late request on Calgary’s Southeast Stoney Trail (SEST) ring road project to design and supply a structure-mounted AIL Sound Wall for one of their 32 recently-constructed MSE Retaining Walls. A solution was needed that would not adjust the wall or change it’s design.

Bowness Park is a century-old island recreation area located on the Bow River in Calgary’s west side. As part of the City’s $10.5 million redevelopment project to preserve the Park’s historical significance and update its amenities, AIL was contracted to design and supply the abutments and wingwalls for an access bridge replacement.
